Study on Deer Antler Growth Behavior of Captive Manchurian Wapiti
摘要
Abstract
From March 8th,2012 to May 22nd,2012,the deer antler growth behavior of a male Cervus elaphus xanthopygus was studied in Beijing Zoo using focal animal sampling method. The sampling intervals were 8-12 days. Different stages of deer antler were taken pictures, the data of the deer antler relative lengths were calculated ,and the deer antler was weighted when amputated. The results showed that the growth of the deer antler main branch of the captive manchurian wapiti was in a ' S' shaped growth curve, which composed by three stages, with time going showed slow, fast and deceleration respectively. The first stage was at 0-29 days of the deer antler trunk growth ,with an average growth rate of 0.17 cm/d. The second stage was at 30-56 days, with an average growth rate of 1.30 cm/d. The third stage was after 57 days,with average growth rate of 0.94 cm/d. The growth rate in three stages were significantly different (P〈0.01).The deer antler was 4.0 kg when sawed after 72 days. The weight increased by 0.05kg/d.The right main branch of the deer antler was 54.5 cm in length, and the average growth rate was 0.76 cm/d. The left main branch of the deer antler was 56.5 cm in length, and the average growth rate was 0.78 cm/d.关键词
